A beverage mixing assembly includes a gasket that is positioned around an open end of a beverage container. The gasket is comprised of a resiliently stretchable material for accommodating a variety of sizes of beverage containers. A housing is coupled to the gasket for gripping the housing and a motor is positioned within the housing. A shaft releasably engages the motor such that the motor rotates the shaft when the motor is turned on. The shaft extending downwardly into the beverage cup when the gasket is positioned around the open end of the beverage container. A mixer is coupled to the shaft such that the shaft rotates the mixer when the motor is turned on thereby facilitating the mixer to mix the beverage in the beverage container.

A method for processing a fluid includes removably securing a retention member to a vessel that bounds a chamber; inserting a collapsible bag within the chamber of the vessel; securing the bag to the retention member so that the bag is supported within the chamber of the vessel; and dispensing a fluid into a compartment of the collapsible bag supported within the chamber of the vessel. The fluid can be mixed within bag while the bag is disposed within the vessel.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.

An assembly for a portable blender. The assembly having a housing that is configured for coupling to a container. The assembly has at least one battery, a motor electrically connected to the battery, a blade coupled to the motor, and a user input device operable to cause power to be sent from the battery to the motor so that the motor rotates the blade. At least a portion of the blade is positioned outside of the housing so that the blade is configured to be positioned in an interior space of the container when the housing is coupled to the container. The assembly may include a plurality of batteries each positioned radially outward from the motor with the batteries positioned circumferentially around the motor. A portable blender including the assembly and a container. The container having a dual-wall, vacuum insulated construction.

Disclosed is a stirring device (D) including a screw shaft (1) driven by a drive unit, the screw shaft (1) being guided with respect to a body by way of a bearing, the stirring device furthermore including a seal (8) rigidly secured to the body and in contact with the ball joint (7) so as to ensure sealing with respect to the fluid to be stirred. The seal (8) is mounted on a seal holder (9), the seal holder (9) including a contact region (10) and being able to take up two positions, a first, operating position in which the seal (8) is in contact with the ball joint (7), and a second, maintenance position in which the contact region (10) is in contact with the ball joint (7).

Described are systems and methods of mixing a liquid in a container, while liquid is being added or removed from the container, and with control of the speed of a mixing device that mixes the liquid to prevent an undesired mixing effect such as splashing, formation of a vortex, foaming, and vibration of a shaft of a mixing device used to mix the liquid.

An agitator assembly includes an agitator body, a shaft and a blocking part. The shaft is assembled to the agitator body and extends through a lead-through in the agitator body into the vessel, when assembled for use, and includes a sealing to seal the rotatable shaft. The blocking part arranged at the agitator body and including a shaft opening through which the shaft is arranged to extend, a mating surface to mate with the shaft which, when brought together by axial movement of the blocking part, provides a seal between the blocking part and the shaft, and the mating surface arranged at an axial distance from the sealing in the lead-through, and when brought together by the axial movement of the blocking part, provides a seal between the blocking part and the agitator body, and that the blocking part provides a closed space around the lead-through in the agitator body.

A drill assembly attachment having a handle, a drill mount, and a throttle. The throttle may have a first portion and a second portion rotationally engaged with the first portion such that the second portion is rotationally actuated in response to linear actuation of the first portion of the throttle. The throttle is positioned with respect to the drill mount and the handle such that the first portion may be linearly actuated by a user with a hand grasping the handle. The drill assembly attachment receives a drill assembly such that the throttle adjustably engages a trigger of the drill assembly. The drill assembly attachment or the drill assembly receives an auger or other tool and the drill assembly attachment with the drill assembly and auger or other tool is used in a method of rotating the auger or other tool.
